To verify their solution, the researchers simulated the propagation of sound waves in a nonlinear medium similar to ...

The TRANSMISSION of acoustic energy through a medium via a SOUND WAVE.. See: SOUND, SPEED OF SOUND.Compare: ACOUSTIC RADIATION. The levels of outdoor NOISE, whether they are intrusive or the normal ...

Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could also be used in technical applications with electromagnetic waves.

Sound waves travel through different types of matter, including liquid water. ... Macroscopic C₅₄₀ model offers new way to study sound wave propagation in topological metamaterials.

Mesoscale eddies can affect how sound waves propagate in the ocean, depending on their size, speed, current direction and location. Understanding these effects are critical for accurate underwater ...

From ETH Zurich: “Schematics of the experimental set-up (left) and wave propagation (right): Waveguide 1 can be heard perfectly by waveguide 3, but not by waveguide 2, and waveguide 3 can be ...

The Institute of Atmospheric Physics develops and operates advanced sound propagation models. In combination with meteorological mesoscale and microscale models they describe the system of atmosphere, ...

Sound and other waves usually propagate equally forwards and backwards. Researchers have now developed a method that prevents sound waves from travelling backwards without deteriorating their ...

Researchers at ETH Zurich have managed to make sound waves travel only in one direction. ... "This concept of loss-compensated non-reciprocal wave propagation is, in our view, ...
